The stuff works

I've used sea foam on lots of cars so I have experience..Put 8 oz in the tank (full tank of gas) and she runs much smoother! This is before I tear open the engine bay and remove the throttle body for a complete cleaning..

You should change oil soon after to get rid of crap that gets into the oil

I don't think that is a Porsche approved fluid.

This could easily be quantified with diagnostic equipment. Does the manufacturer provide any of this analysis? I'm always skeptical when a company tells you'll "feel" the difference straight away.
To me that's like a hair tonic where they just add menthol and make you believe your hair is lush and thick now since you feel the tingle.

I use sea foam in my lawnmower and weed wacker. It seems to cut through the gunk from reformulated gas. I have also put it in the tank of some old British cars I have. Seems to make them run smoother after a winter in the garage. Never used it in the Boxster. Is my memory deceiving me or was there a discussion years ago about people using techron fuel injection cleaner in their boxsters and loving it?

That being said, just like a humans arteries can clog up over time from the junk we eat, there is medicine that can help clear those clogs. No reason to suppose this isn't the same concept on the automotive side.

There are also pills that make you lose weight

Yeah, and just like those pills....I've got some land down in Florida.....

Maybe a better comparison - seafoam is more like Ex-lax?

Seafoam is great for cleaning carbon deposits. I used it for cleaning the SAI air ports going into the headers with fantastic results.

I sure hope putting something in the gas tank doesn't leak into the oil...I'd really have problems. I have great results with seafoam! Seafoam is a cleaner and lubricant originally developed for Marine use. Those outboard motors get real gunked up! Put some on your fingers and see for yourself how slippery it is. But don't rub your eyes afterward. Ha ha..

I'm a little skeptical. The sea foam instructions are basically telling you to do an "Italian tune-up", go out and run the car hard to heat it up and blast the crud out of your motor. Also, the difference in carbon before and after was negligible to my eye.

I'm a believer of Seafoam. Used it in motorcycles for years. Avoids/repares sticky valve disease, gas stabilizer in winter too.

I've heard of using it to flush crankcase too.

Smile Seafoam

This is a waste of time and money...used it on my other cars..no effect.
No way will I put it on my Boxster...no such thing as cure in a can, proper maintenance and tuneup is the only way to go!
Just my opinion and experience, then again if it satisfies your curiosity, go for it!

cure in a can

Back in the early 80's I've used Slick50 as per advertised, looking back didn't really make any difference,especially now Synthetic oil.
It's Big Business, if people want to try them go ahead! But don't dxpect a drastic change or a perceived advantage of extra protection!
I am not an engineer, just talking from experience.. Now if Porsche recommends and back them up, then this will Totally be a new discussion and I'll leave it at that.

having worked on cars on and off for 30+ years, I have found some of these additives are helpful. there are cases of carbon build up and fuel injector clogging (prior to full blockage) which will be helped by using these things. if there is a mechanical problem or no problem at all these will not help. everyone here is always changing water pumps and ims bearings, but there are no performance advantages to changing these before they fail, the car still runs the same. the same is true with these cleaners, if the engine is not dirty, they will do nothing. some like to call these products snake oil, but if you need to lubricate a snake, it might be just what you need.....
